Health inspection at ExTEL Optoelectronics case site to increase power generation

General Manager Chen Jinxiong said that ExTEL pioneered the field testing package service, with as many as 8 to 10 inspection items. It can complete 1 MW field testing in one day and issue a report to provide improvement suggestions, clearly listing the urgent and long-term needs. Risky projects. Take the photovoltaic system of Chengyi New Energy's Chiayi chicken coop as an example. The site has been connected to the grid for more than four years and has undergone two health inspections. The owner made repairs based on each health inspection report to improve the power generation and quality of the site.

Li Weijia, general manager of Chengyi, pointed out that power plant owners receive electricity bills regularly every month and are not alert to the power generation losses caused by poor equipment or neglected maintenance. "Most power plants can actually earn more." For Ai Site's regular health check-up service is highly recommended.

ExTEL's health inspection items include inspection of module power attenuation, verification of sunshine meter readings, inverter performance testing, DC box thermal development, string I-V characteristic curve measurement, string insulation resistance testing, grounding continuity testing, etc. . Drones are also used to conduct IR inspections, and conditions such as module shading, damage, hot spots, and no power generation are all revealed. The integrity is unmatched by professional maintenance operators.

In addition, ExTEL has developed a solar case dust detection system (DAS2.0), with hundreds of units installed across Taiwan. It can monitor the loss of power generation due to dust on the case site, accurately judge the cleaning time, reduce the waste of cleaning resources, and improve power generation operations. receive. The machine adopts a plug-and-play design and is easy to install. It also provides an exclusive monitoring webpage and guarantees a 20-year service life. DAS2.0 is suitable for decentralized solar installations. For large installations on the ground, multiple DAS2.0 units can be used to monitor dust in zones and clean the dirtiest areas to reduce cleaning costs.

ExTEL's strong technical capabilities have been recognized by Taiwanese customers and also favored by the Dutch Kiwa Group. In May, it became a member of Kiwa. Kiwa has also previously acquired Kiwa PVEL in the United States and Kiwa PI Berlin solar module laboratory in Germany. It has rich experience and energy in testing, inspection and certification. ExTEL will leverage the group's resources to serve Taiwanese customers and also assist Kiwa in expanding the Asia-Pacific market. Kiwa is an internationally renowned testing, inspection and certification (TIC) company, and is also an authoritative organization for energy storage equipment certification and testing in Europe. In response to the take-off of Taiwan's energy storage industry, energy storage equipment certification and testing will become a key business of ExTEL in the future.

Europe has a large amount of energy storage construction and accumulated rich experience, making it the best candidate for Taiwan to learn from. Chen Jinxiong, general manager of ExTEL, said that the energy storage equipment is inspected at the point of purchase. Through strict technical training by Kiwa, the ExTEL team will provide high-quality services to Taiwanese customers with local manpower.
